IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 204, 306, dated May 28,1878 application filed April 30, 1878.

To all whom it may concern:

Be it known that I, EDWIN S. DRAKE, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Lamps; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawing, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to the class of lamps in which the reservoir islocated away from the burner; and it consists in a hooked lever foroperating the valve and for locking the reservoir, said lever beingoperated by a rod, and in the construction of parts, as will behereinafter more fully set forth.

In the annexed drawing, Figure l is a vertical section of the reservoirand exterior cup, showing my invention applied thereto. Fig. 2 is abottom view of the reservoir. Fig. 3 is a plan view of the outside cup.Fig. 4 is a part side view and part section of the lower part of thereservoir.

A represents the outside cup or shell, provided at or near the bottomwith a pipe, B, for conveying the oil to the burner.

0 represents the reservoir, provided in the center of its bottom with adownwardly-projecting tube or collar, D, through which is passed thecylindrical valve F. This valve is open at the bottom, closed at thetop, and provided with side openings or a. A pin, b, projects through aslot, or, in the collar D, to guide the valve in its up-and-downmovement.

At the bottom the valve F is provided with a cross-bar, b, from whichproject two ears, and between these is pivoted the inner end of a lever,G. This lever is hung on a pivot in an arm, H, projecting from the underside of the reservoir, and from the outer end of the said lever extendsa flat bar, I, up between the cup and reservoir, as shown.

In the lower edge of the lever G is formed a hook, d, at a point a shortdistance inward from the point of connection of the lever with the armH.

Above the bottom of the cup A is a ring, L, connected to the bottom bytwo or more arms, 0, or in any other suitable manner. When the reservoiris filled, by pulling the rod I the valve F is closed, when thereservoir is inverted and placed in the cup A down to it's place. By nowpushing down the rod I, the valve F is opened to allow the oil to passout of the reservoir, and at the same time the hook (1 passes under thering L, and thereby locks the reservoir in place.

To remove the reservoir, the rod I must be pulled upward to release thehook d from the ring L, and this movement of the lever G closes thevalve F.

At no time is it necessary to move either the reservoir or case forlooking or unlocking, or for opening or closing, the valve. By passingthe rod I on the outside of the reservoir all necessity of perforatingthe same is avoided.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A vertical rod arranged on the outside of the reservoir, incombination with a valve at or near the bottom of the reservoir, wherebythe valve may be opened and closed without moving the reservoir or case,as herein set forth.

2. A vertical rod arranged on the outside of the reservoir, incombination with a looking device, whereby the reservoir may be lockedand unlocked without moving the reservoir or case, as herein set forth.

3. The combination of a vertical rod arranged on the outside of thereservoir, a valve at or near the bottom of the reservoir, and a lockingdevice, whereby, at one operation, the valve may be opened and reservoirlocked, or the valve closed and reservoir unlocked, without moving thereservoir or case, as herein set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.

EDWIN S. DRAKE.
